FTS - Full Text Index/Alias - Creating index docs page has been purged

The Create/Edit tab in the Full Text Indexes/Aliases section of the UI contains a link to docs having information about the same is missing. The error observed is Page Not Found on the docs site.

So, this exists ..

https://docs.couchbase.com/server/6.6/fts/fts-creating-indexes.html

while this doesn't ..

https://docs.couchbase.com/server/7.0/fts/fts-creating-indexes.html

We've already shipped 7.0, 7.0.1, 7.0.2 with builds pointing to the above link. So I don't see any other option here than adding it back.
